What is the "Microsoft Teams Chat Files" folder that OneDrive automatically creates?

Q. A folder is automatically created in OneDrive. What kinds of files are stored in the "Microsoft Teams Chat Files" folder?

A. The "Microsoft Teams Chat Files" folder stores files uploaded in Teams Chat.

If Teams is set to Japanese, files are saved in "Microsoft Teams チャット ファイル"; if set to English, they are saved in "Microsoft Teams Chat Files".
 

Regardless of the Teams language, when you use Loop components in Teams chats or add files from the mobile app, the content is saved to "Microsoft Teams Chat Files".

Files uploaded in Teams "Chat" are saved to OneDrive, while files uploaded in "Teams" (channels) are saved to SharePoint.

Additionally, the following files are saved to OneDrive.

• "Microsoft Copilot Chat Files"
  When you upload files in Microsoft 365 Copilot Chat, OneDrive creates a "Microsoft Copilot Chat Files" folder as the storage location.
   
• "Apps"
  Files uploaded by respondents in Microsoft Forms are saved in a "Microsoft Forms" folder that is automatically created inside the "Apps" folder.

• "Notebooks"
  When you open OneNote from the Microsoft 365 Home app list and create a new notebook, a "Notebooks" folder is created as the storage location.
   
• "Whiteboards"
